As I end the refrain, thrust home. – +200% melee damage and fixed melee accessory. Reduced damage.
Curse of the Porcelain Fist! – The user takes increased damage from melee attacks.
Usage & Description
Rapier has the highest melee damage modifier in the game but has much lower gun damage than similar quality assault rifles. It is a good choice for melee-focused characters such as Zer0 with a Bloodshed build. The drawback is something that can be easily managed, as incoming melee attacks can be easily avoided, and bullet damage to the user is not increased.
When paired with a powerful roid shield and the Many Must Fall skill, this weapon can wreak havoc on groups of enemies while keeping Zer0 permanently cloaked.
Krieg, enhanced with Mania, also makes effective use of the Rapier as the melee bonus allows him to do heavy melee damage outside of Buzz Axe Rampage, and the 'porcelain fist' curse allows him to regenerate his action skill even more quickly than normal. As the mania tree puts very little stock in ranged attacks, excluding the thrown buzz-axes in Buzz-Axe Rampage, the gun's ranged capabilities are of no concern.
Outside of the mentioned scenarios, the Rapier is generally surpassed by other weapons. However, one powerful ability of the Rapier is that the Melee damage modifier works at all levels and will scale with the character's melee damage, so even a low-level rapier works well even at OP10, where low-level ranged weapons can't and new ones must be acquired.
The Rapier is one of the few weapons in Borderlands 2 which is not restricted to be able to spawn with just 1 accessory, instead, the Rapier always spawns with a unique bayonet attachment in the 2nd accessory slot; leaving the 1st slot open to all the other accessory variants. The regular bayonet attachment cannot spawn on slot 1 for more melee damage bonus.
The Rapier can only spawn with either the Vladof or Torgue scopes or none at all.
The quote is from the play Cyrano de Bergerac in which the title character mocks his opponent during a duel by composing a poem at the same time.
